Cateye diode laser CEL
The MOGLabs cateye diode laser offers a new twist in external cavity diode lasers. A cateye reflector and ultranarrow filter replace the alignment-sensitive diffraction grating of conventional Littrow and Litman-Metcalf designs.
The CEL is robust, stable, and acoustically inert. You can literally hit it with a hammer and it will stay locked, and it is inherently self-aligning so you can tune tens of nanometres without having to realign. In combination with MOGLabs electronics, the linewidth can be well below 100 kHz. Many laser diode wavelengths are available, for example 420-425nm, 460-470nm, 492/493nm, 520nm, 633-639nm, 657nm, 671nm, 689nm, 698nm, 729nm, 767nm, 770-820nm, 820-895nm, 920-935nm, 960nm, 1010-1016nm, 1033nm, 1092nm, 1120nm, 1550nm, 1612nm at powers up to 200mW extra‐cavity.
Enjoy the rock-solid stability normally expected only from DFB and DBR diodes – but with wide-range tunability, order-of-magnitude smaller linewidth, broader range of wavelengths, much lower sensitivity to optical feedback – and much lower diode cost.
The datasheet for the CEL002 is available here. Further details and product manual can be found under SUPPORT.
See performance data for typical test results.
CEF extended cateye diode laser
The MOGLabs cateye diode laser is also available in an extended chassis which allows internal mounting of a Faraday isolator, and single-mode fibre coupling. Fibre coupling is extremely simple and stable using two mirrors (or one mirror and PBS beamsplitter cube, for access to a second beam for frequency stabilisation). We typically use Schafter+Kirchhoff couplers as shown but can also use Thorlabs FiberPort adapters. Coupling efficiency is over 70% with near infra-red diodes.
